and l?. Both the pipes 9 and 17 are provided `with hand valves 20 and 2l, respectively, on the side ot the pipe 18 away from the agitating tank. The pipe i7 1neymud the coninenting ripe i8 is extended to project at 22 Within t ie pipe 6 atv the lower end of the splitting-tank, as shown in the drawing. Within the pipe 6 the pipe 1 7 is curved upending in a nozzle Q3 for discharlg-l ingair upwardly into the material Within the tank. The air thus introduced will hubhle up through the mass of oil and causen circulation oi the oil in the pipe 6 to prevent lodging ol".a untreated oil 1n that portion oi the The entrance ot the air troni this pipe into the tank may be controlled hy o handvalve 2li immediately outside oi the tenir.

in the treatment ot the oil by means oi the heated air, volatile. material separated from the mass of the oil Will arise tothe upper end of theA tank along. with the air used in treating the oil and will pass upwardly through an outlet pipe 25. To condense the volatile constituents-in this es- Coping gas l provide a dome-shaped con denser 26 through 'which the pipe 25 will Iproject upwardly s short distance, thus providing an annular pan or receptacle 2'? between the walls ofthe condenser and the pipe 25. Clutside the condensingT chamber 26 is a cooling chamber 28 Which provides' between the Walls oit the chambers 26 and 28 a space for the circulation of the cooling liquid. This liquid is introduced through a valve-controlled pipe 29 toward the lower end thereotythe said cooling` liquid passing outwardly at the upper end of the chamber 28 through the pipe 30. This pipe 30 serves -to connect the chamber 28 with a second auxiliary cooling chamber 3l. The said chamber 3l is preferably a lenoth oifpipe ot" large diameter through u'hicn the 'coolingA liquid may circulate and be draivn out through an outlet pipe 32 atthe opposite end from the inlet.

rlh'e volatile material condensed Withinthe chamber 26 Will run down the Walls ot the said chamber and collect in the container 27 at the lower end thereotl and may then be run off through an outlet pipe 33 loading longitudinally through the cooling pipe 8l and from thence downwardly to a container 34: `adapted to receive and collect the condensed material. `At the lower cud ot the container 34 l have provided a so-called sucker or injector 1to1' drawingl the condensed material fromjthe container 3d and discharging it into the agitatng tank. This sucker comprises a connection between the container and the pipe 17' through a valvecontrolled pipe 35. At the point where the pipe 35 connects with the cold air pipe 1T I Leimen prefer to constrict the passage" in pipe 17` somewhat, as shown at 3G, so as to obtain aA greater velocity oi projection of the air in order to draw the condensed liquid from the the pipe i2 until the level has reached the'` point desired. Air from the hot air pipe 9 is then turned on, the blow-oll' nozzles lll heing open and the valves 16 closed. At o point in .the pipe Sjadjacent the discharge pipe 12, I provide a cup flprojecting slightly into the pipe 9 and adapted to receive oil therein into which oil may be /introduced a thermometer to ascertain the temperature of the air in theA pipe. l/Vhen the air has been discharged through lthe blow-oli' nozzles 14 until the pipes have been thoroughly cleaned and the temperature is found to be at the desired point, the blovv-olf nozzles are closed and the valvesl 1 6 opened. The heated air is then discharged into the tank. The discharge of the air through the nozzles 13 into the lower ends oi the pipes Il Will act A with un' injector effect to'draw the oil into the lower ends ot the pipes e and carry it'- upwardly with the blast of air through the pipes and discharge it downwardly upon the upper surface of the oil in the tank.' A circulation'ol the oil in the. tank will thus be secured and in a short period of time the total mass of oil in the tank Will have been circulated through the pipes 4 and be there acted upon thoroughly by its Contact with the heated air. The action ot the air upon the oil will be to break up'the molecules in such manner vthat the oil will become more It is thought that the oxygen of the A iiuid. air Will slightly oxydize the oil and that the complex hydrocarbon molecules Will be recombined with the/oxygento form amore fluid and mobile yrI'1ass,Which rex. fins fluid after it becomes cold.

The valve 21. in the cold a'ir pipe will ordinarily be closed Whenthe temperature of the .air is regulated ,in the 'pipe 9. The valve 19 in the connecting pipe will be' open so-that the air from the pipe {l} will also be discharged through the connecting pipe 18,

the pipe 17 and the discharge nozzle 'into the lower part of the tank. If, however, the temperature of the/ air rises beyond the desired point, the valve 2l in the cold-air pipe.inay be opened and thus allou a/,discharge of the cold air through,the connectles and means connecting said wnmiuer m air- A discharge so that thank-discharge will draw said condensed maerial therefrom and discharge it into said tank.
